An access control system is fundamentally a security measure that regulates entry and exit to specific areas or systems. Its primary function is to ensure that only authorized individuals can access certain physical spaces or confidential information, thus enhancing overall security. This can involve a variety of technologies and methods, such as key cards, biometric scanners, or PIN codes, designed to verify and authenticate individuals before granting them access.

The other choices, while related to security and management systems, do not capture the essence of an access control system. Communication management pertains to different forms of data exchange, a monitoring system for CCTV focuses specifically on surveillance without necessarily controlling access, and an emergency alert system is designed for notification during crises rather than regulating entry. Thus, the definition as a measure regulating entry and exit accurately describes the function and purpose of an access control system.
